Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP4
The NM_006231.4(POLE):c.4889G>A(p.Arg1630Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000273 in 1,613,436 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1630W) has been classified as Uncertain significance.

not provided Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jun 29, 2022 | In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Has not been previously published as pathogenic or benign to our knowledge - |
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 28, 2024 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1630 of the POLE protein (p.Arg1630Gln). This variant is present in population databases (rs750180239, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 540689). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt POLE protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 06, 2024 | The c.4889G>A (p.R1630Q) alteration is located in exon 37 (coding exon 37) of the POLE gene. This alteration results from a G to A substitution at nucleotide position 4889, causing the arginine (R) at amino acid position 1630 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
